Purpose To compare CT texture features of benign and malignant ovarian lesions and to build a machine learning model to detect malignancy in incidental ovarian lesions. The radiologic findings of commonly encountered incidental ovarian lesions on ultrasonography or computed tomography are described and the management plan according to the stratified risk for malignancy in each ovarian lesion is explained. There should be no internal vascularity on Doppler ultrasound or internal enhancement on CT or MRI. For . The prevalence of adnexal cysts initially detected at CT was 2763 (6.6%) of 42 111 in our large cohort of patients who underwent CT for non-adnexal indications and who had no prior known cyst, with 18 (0.7%) of the 2763 patients with cysts being given a diagnosis of ovarian cancer within a median of 5 years of follow-up.
